CHECK CYLINDER COMPRESSION
(a) Insert a compression tester into the spark plug hole.
(b) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine revolutions
of 250 rpm or more.
(c) Repeat steps (a) through (b) for each cylinder.
NOTICE:
This measurement must be done in as short a time as possible.
Standard pressure:
1,079 kPa (11.0 kgf/cm2, 156 psi) or more
Minimum pressure:
883 kPa (9.0 kgf/cm2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm2, 14 psi) or less
(d) If the cylinder compression in 1 or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (b) for
the cylinder with low compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are probably
worn or damaged.
If pressure stays low, a valve may be sticking or
seating improper, or there may be leakage past the
gasket.

Check for proper installation.
Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see if
either camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock.
(d) If there is wear or damage on only one side of the belt,
check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and check gasket has been installed
correctly and for foreign material on the pulley teeth.
If necessary, replace the timing belt.

Using a drill, make a hole in the cylinder as shown to
release the gas inside.
CAUTION:
The gas coming out is harmless, but be careful of the chips
which may fly up when drilling.

INSPECT VALVE CLEARANCE
Check only those valves indicated in the illustration.
Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
Record the valve clearance measurements of those
that are out of specification. They will be used later
to determine the required replacement adjusting
shim.
Valve clearance (Cold):
Intake 0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.)
Turn the crankshaft pulley 1 revolution (360°), and align
the groove with timing mark ”0” of the No.1 timing belt cover.
Check only the valves indicated as shown. Measure the
valve clearance. (See procedure in step (a))

Determine the replacement adjusting shim size according
to the following Formula or Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate the thickness of a new shim so the valve
clearance comes within specified value.
T .......... Thickness of used shim
A .......... Measured valve clearance
N .......... Thickness of new shim
Intake
N = T + (A - 0.20 mm (0.008 in.))
Exhaust
N = T + (A - 0.30 mm (0.012 in.))
Select a new shim with a thickness as close as possible to the calculated values.
HINT:
Shims are available in 17 sizes in increments of 0.050 mm

CAUTION:
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer.
Exercise caution in order to minimize the length and
frequency of contact of your skin to used oil. Wear
protective clothing and gloves. Wash your skin thoroughly with soap and water, or use water-less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.
In order to preserve the environment, used oil and
used oil filters must be disposed of only at designated disposal sites.
